At Hive13, we made our stamp with our 60W laser cutter by engraving linoleum blocks. They turned out pretty well: <a href="http://www.hive13.org/?p=395">http://www.hive13.org/?p=395</a><div><br></div><div>If anyone has a 60W laser, these are the power settings we used: <a href="http://wiki.hive13.org/Laser_Settings#Speedball_Linoleum_Block_.283mm_thick_Linoleum.29">http://wiki.hive13.org/Laser_Settings#Speedball_Linoleum_Block_.283mm_thick_Linoleum.29</a></div>

<br>
Now that Mitch's passports are everywhere and our space has just voted<br>
on a new logo, it's about time we made a stamp. But how to fabricate<br>
one? I googled around for what other spaces had done and all the ones I<br>
saw just did a design and sent it out to a commercial stamp manufacturer.<br>
That doesn't seem very hackerspacey to me.<br>
<br>
So, does anyone have tips to share on making your own? What materials<br>
work best, just rubber (what sort?) or something else? We have a CNC<br>
mill and a 40W CO2 laser cutter/engraver. Can you mill rubber without<br>
just making a mess, can you laser engrave it deep enough to create a<br>
usable stamp, if so what sort of settings did you need? Or is there a<br>
way more low-tech process for spaces without these tools to use, that<br>
still gets great results?<br>
<br>
Tips welcome, then I will run some experiments and post our results.<br>
<br>
